BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a pallet. In particular, the present invention relates to a paper pallet.

2. Description of the Related Art

Paper pallets are more widely used than conventional wooden pallets and metal pallets, as the paper pallets are light, inexpensive, and recyclable. FIG. 1 of the drawings illustrates a typical paper pallet made of corrugated paper and comprising a top plate 90 and a bottom plate 92 supporting the top plate. After cargo is placed on the top plate 90, the cargo is tied up with a strip made of, e.g., polyethylene. However, the strip in a tightened state is apt to bite a front edge 91 and a rear edge of the top plate 90, resulting in damage to the paper pallet and even falling of the cargo. Further, the damaged front and rear edges 91 might cause injury to the workers.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 2 illustrates an embodiment of a pallet in accordance with the present invention. The pallet comprises a top plate 10, a bottom plate 20, and a plurality of spacers 30 mounted to a general plane of an underside of the bottom plate 20. The illustrated pallet is made of corrugated paper. It is, however, noted that the pallet can be made of any other suitable material.

As illustrated in FIGS. 2 and 3, the top plate 10 comprises a main section 11 forming a top side of the pallet. The top plate 10 further includes two enveloping sections 14 and 15 respectively on two sides of the main section 11, with a protective folding section 12, 13 being provided between each enveloping section 14, 15 and the main section 11.

As illustrated in FIG. 4, the enveloping sections 14 and 15 are folded downward and inward, with at least one reinforcing plate (two reinforcing plates 16 and 17 in this embodiment) being sandwiched between the main section 11 and the enveloping sections 14 and 15. The protective folding sections 12 and 13 form front and rear edge of the top plate 10 to prevent damage to the top plate 10 when a cargo is placed on the top plate 10 and tied up with a strip.

Referring to FIG. 5, the bottom plate 20 includes a plurality of recessed sections 21. The spacers 30 are parallelepiped and bonded in the recessed sections 21. Further, each of two sides of the bottom plate 20 includes an enveloping section 22 that is folded inward to cover an associated recessed section 21. FIG. 6 illustrates a modified embodiment of the bottom plate 20, wherein each enveloping section 22 includes an insertion section 23 that is folded downward and inserted into the associated recessed section 22 and sandwiched between the associated spacers 30 and a sidewall of the associated recessed section 22.

FIG. 7 illustrates a modified embodiment of the pallet in accordance with the present invention. In this embodiment, the pallet comprises a top plate 100, a bottom plate 40, and a plurality of rows of spaced spacers 30 mounted to a general plane of an underside of the bottom plate 40. The pallet is so constructed that two forks (not shown) of a forklift (not shown) can be extended through either a longitudinal direction of the pallet or a transverse direction of the pallet, and the cargo can be tied up along either the longitudinal direction or the transverse direction of the pallet without causing damage to the pallet.

In this embodiment, as illustrated in FIGS. 7 through 11, the top plate 100 is substantially the same as the top plate 10 in the embodiment shown in FIG. 2. More specifically, the top plate 10 comprises a main section 11 forming a top side of the pallet. The top plate 10 further includes two enveloping sections 14 and 15 respectively on two sides of the main section 11, with a protective folding section 12, 13 being provided between each enveloping section 14, 15 and the main section 11.

The bottom plate 40 includes a main section 41 below the enveloping sections 14 and 15 of the top plate 100. As illustrated in FIGS. 8 and 9, the bottom plate 40 includes an enveloping section 45 on each of two sides thereof, with a protective folding section 43 being provided between each enveloping section 44, 45 and the main section 41. As illustrated in FIGS. 9 and 10, the bottom plate 40 extends along a direction parallel to the extending direction of the folding sections 12 and 13 of the top plate 100. Referring to FIGS. 9, 10, and 11, each enveloping section 44, 45 outside the main section 11 of the top plate 100 is folded upward and inward to be inserted and sandwiched between the upper reinforcing plate 16 and the main section 11 of the top plate 100. The protective folding sections 43 of the bottom plate 40 form the left and right edges of the pallet to prevent damage to the pallet when the cargo is tied up along the transverse direction of the pallet whereas the protective folding sections 12 and 13 forms the front and rear edges of the pallet to prevent damage to the pallet when the cargo is tied up along the longitudinal direction of the pallet. Each enveloping section 44, 45 may include a folding line to assist in insertion of the enveloping sections 44 and 45.

The pallet in FIG. 7 further includes a moisture-proof members 50 attached to an underside of an associated row of spacers 30.
